Lanun V3
Lanun V3 — a MetaTrader 4 expert advisor (trading robot) kept in the Old Kings collection. This copy is version 3.

It has 17 settings, for example MMType (default 1), Max Trades (default 250) and Lots (default 0.01). Watch it on a demo account for a while — robots can behave differently with each broker.
